A bright, narrow stream of particles traveling through the Sun's corona,
visible in images taken with a coronagraph or during a total solar
eclipse. Coronal streamers represent the most outwardly extended
structures in the solar corona and result from the interaction between
the solar slow wind and the large-scale magnetic field.
→ helmet streamer.

A large-scale → coronal feature with apparent
→ cusp, seen during a
→ solar eclipse. They usually arise from
→ sunspots and → active regions,
so at the base of a helmet streamer one will often find a
→ prominence.
They form magnetic loops that connect the sunspots and suspend
material above the surface of the Sun. The magnetic field lines trap
the material to form the streamers. The action of the
→ solar wind is at
the origin of the peak feature.
